We have stored the bus with tank dry, then just before a camping trip, fill
with fresh water from clean garden hose specifically used for filling the
tank.  Put in 1/4 of bleach, slosh around, run through the faucet for about
5 minutes, drain and refill.  Always good to go.  Been drinking that water
for years, no incidents.  Love having fresh running water on board!  Once
per year, I usually clean the level measurement points with a baking
soda/water paste to keep them reading true.
